Poor service and too many issues after purchasing the vehicle.

I bought a Renault Kwid in September and there seems to be a new problem every week. The branch took the vehicle for service late, after they had missed a few service due dates. The first issue I had was with the battery, two weeks after I had purchased the vehicle, then I had to replace the wiper, then the door handle on the driver’s side was broken, and now there’s an issue with the exhaust pipe. It’s only been 6 weeks since I’ve had this vehicle and it doesn’t give me peace of mind. When I spoke to some guy at the branch over the phone, he was very rude today. He said “I’m not gonna keep repeating myself over and over again” How do you address a client like that and think it’s okay? They seem to only care about the client when it comes to making the sale, but afterwards you don’t get quality service. At first I thought I would recommend the branch to anyone but now I would definitely not recommend it. The general manager does not respond to emails, the only person who assists me is the salesman, Mahlatse.
